Abstract

The molar absorptivities of Pb²⁺, PbCl⁺, PbCl₂, and PbCl ⁻₃ were obtained between 210 and 300 nm. Molar absorptivity data were used to determine lead speciation directly from Pb(II) absorbance characteristics in a variety of media including natural seawater. The absorbance characteristics of lead in a particular chloride medium reveal the lead chloride formation constants appropriate to that medium. Our analyses indicate that lead chloride formation constants are significantly smaller in MgCl₂ media than in HCl at constant ionic strength.
